www.hyperionics.com they have something called hyper cam it is supposed to be able to film anything running on your screen. I have hyper snap and it takes great on the fly screen shots from GF cinematics, so I am sure hyper cam will work. it is a reasonable price for those who have money, I bought my copy of hyper snap, had i the doss at the time i would have bought hyper cam too.
(this by the way is a mayhaps hint for anyone with the program who feels shall we say cyber philanthropically inclined in natue. wink, wink.)
try this it may be the thing which does it for you.
